Radiators should work pretty well, and large solar panels can do double duty as radiators.
Also, curiously, newer GPUs are developed to require significantly less cooling than previous generations. Perhaps not so coincidentally?
That makes radiating a much more practical approach to cooling it.
The great thing about your argument is that it can be used in any circumstance!
Cooling car batteries, nope can't possibly work! Thermodynamics!
Refrigerator, are you crazy? You're fighting thermodynamics!
Heat pump! Haah thermodynamics got you.
Right now only upsides an expensive satellite acting as a server node would be physical security and avoiding various local environmental laws and effects
You are missing some pretty important upsides.
Lower latency is a major one. And not having to buy land and water to power/cool it. Both are fairly limited as far as resources go, and gets exponentially expensive with competition.
The major downside is, of course, cost. In my opinion, this has never really stopped humans from building and scaling up things until the economies of scale work out.
> connect to other satellites and earth
If only there was a large number of satellites in low earth orbit and a company with expertise building these ;)
These satellites will be in a sun-synchronous orbit, so only close to any given location on Earth for a fraction of the day.
It's interesting that you bring that up as a benfit. If waterless cooling (i.e. closed cooling system) works in space, wouldn't it work even better on Earth?
Your examples prove our case. You just must not understand how they work
Yes, running hotter will cause more energy to be radiated.
but
These parts are not at all designed to radiate heat - just look at the surface area of the package with respect to the amount of power they consume.
Hmm, surely the radiator can run at arbitrary temperatures w.r.t. the objects being cooled? I'm assuming heat pump etc is already part of the design.
